MedTech companies need to accelerate their digital strategies and integrate digital solutions into their principal business plans if they are to maintain and enhance their position in an increasingly solution orientated healthcare ecosystem. With growing focus on healthcare value and outcomes and continued cost pressures, MedTechs need to get the most from their current portfolios to drive profitability. An area where significant improvements might be made in the short term is in MedTechs' customer facing supply chains. To achieve this, manufacturing companies need to make digitization and advanced analytics a central plank of their strategies.

In this Commentary

This Commentary describes the necessity for MedTechs to enhance their digitization strategies, which are increasingly relevant, as MedTech companies shift from production to solution orientated entities. In a previous Commentary we argued that MedTechs history of strong growth and healthy margins make them slow to change and implement digital strategies. Here we suggest that the business model, which served to accelerate MedTechs' financial success over the past decade is becoming less effective and device manufacturers need not only to generate value from the sale of their product offerings, but also from data their devices produce so they can create high quality affordable healthcare solutions. This we argue will require MedTechs developing innovative strategies associated with significantly increasing their use of digital technology to enhance go-to-market activities, strengthen value propositions of products and services and streamline internal processes.

MedTechs operate with an outdated commercial model

Our discussion of digitization draws on two international benchmarking studies undertaken by the Boston Consulting Group (BCG). The first, published in July 2013 and entitled, “Fixing the MedTech Commercial Model: Still Deploying ‘Milkmen’ in a Megastore World” suggests that the high gross margins that MedTech companies enjoy, particularly in the US, hide unsustainable high costs and underdeveloped commercial skills. According to BCG the average MedTech company’s selling, general and administrative (SG&A) expenses - measured as a percentage of the cost of goods sold - is 3.5 times higher than the average comparable technology company. The study concludes that MedTechs' outdated business model, dubbed the “milkman”, will have to change for companies to survive.

BCG’s follow-up 2017 study

In 2017 BCG published a follow-up study entitled, “Moving Beyond the ‘Milkman’ Model in MedTech”, which surveyed some 6,000 employees and benchmarked financial and organizational data from 100 MedTech companies worldwide, including nine of the 10 largest companies in the sector. The study suggested that although there continued to be downward pressure on device prices, changes in buying processes and shrinking gross margins, few MedTech companies “have taken the bold moves required to create a leaner commercial model”.

According to the BCG’s 2017 study, “Overall, innovation productivity [in the MedTech sector] is in decline. In some product categories, low-cost competitors - including those from emerging markets - have grown rapidly and taken market share from established competitors. At the same time, purchasers are becoming more insistent on real-world evidence that premium medical devices create value by improving patient outcomes and reducing the total costs of care”. The growth and spread of value-based healthcare has shifted the basis of competition beyond products, “toward more comprehensive value propositions and solutions that address the entire patient pathway”. In this environment, MedTechs have no choice but to use data to deliver improved outcomes and a better customer experience for patients, healthcare providers and payers.

MedTech distributors increasing their market power and influence

Although supply chain costs tend to be MedTechs' second-highest expense after labour, companies have been reluctant to employ digital strategies to reduce expenses and increase efficiencies. As a consequence, their customer supply chains tend to be labour intensive relationship driven with little effective sharing of data between different territories and sales teams. Customer relations are disaggregated with only modest attention paid to patients and payors and insufficient emphasis on systematically collecting, storing and analysing data to support value outcomes.

As MedTech manufacturers have been slow to develop strong and effective data strategies, so MedTech distributors have increased their bargaining power through M&As and internationalisation. Some distributors have even assumed marketing, customer support and education roles, while others have launched their own brands. MedTechs' response to these changes has been to increase their direct sales representatives. However, consolidation among buyers - hospitals and GPOs - and the extra downward pressure this puts on prices, is likely to make it increasingly costly for MedTechs to sustain large permanent sales forces.

Advantages of distributors but no way to accurately measure sales performance

Notwithstanding, the distributor model is still common with MedTechs and has been successful in many markets for a long time. Independent distributors are often used when producers have small product portfolios. In smaller markets, distributors are employed primarily to gain economies of scale as they can combine portfolios of multiple companies to create a critical mass opportunity and obtain better and faster access to markets.

MedTechs have a history of investing in sales force effectiveness (SFE) typically to increase the productivity of sales representatives. Sales leaders have some indication that this pays-off through incremental revenue growth and profits, but they struggle to assess the true performance of such investments not least because SFE includes a broad range of activities and also it is almost impossible to obtain comparative competitor data.

Changing nature of GPOs

GPOs also have changed. Originally, they were designed in the early 20th century to bring value to hospitals and healthcare systems by aggregating demand and negotiating lower prices among suppliers. Recently however they have raised their fees, invested in data repositories and analytics and have been driving their models and market position beyond contracting to more holistic management of the supply chain dynamics. Notwithstanding, many GPOs are struggling to change their model based on aggregate volume and are losing purchasing volume amid increasing competition and shifting preferences.

New entrants

The changing nature of MedTechs' customer supply chain and purchasers increasingly becoming concerned about inflated GPOs' prices have provided an opportunity for data savvy new entrants such as OpenMarkets. The companyprovides healthcare supply chain software that stabilizes the equipment valuation and cost reduction and aims to reinvent how healthcare providers and suppliers work together to improve the way healthcare equipment is bought and sold. OpenMarkets’ enhanced data management systems allow providers to better understand what they need to buy and when. The company represents over 4,000 healthcare facilities and more that 125 equipment suppliers; and provides a platform for over 32,000 products, which on average sell for about 12% less than comparable offerings. In addition, OpenMarkets promotes cost efficiency and price transparency as well as stronger collaboration between providers and suppliers.

Amazon’s B2B Health Services

But potentially the biggest threat to MedTech manufacturers, GPOs and distributors is Amazon’s B2B Health Services,which is putting even more pressure on MedTechs to rethink their traditional business models and to work differently with healthcare providers and consumers. With a supply chain in place, a history of disrupting established sectors from publishing to food and a US$966bn market cap, Amazon is well positioned to disrupt healthcare supply chain practices, including contracting. In its first year Amazon’s B2B purchasing venture generated more than US$1bn and introduced three business verticals: healthcare, education and government. Already, hundreds of thousands of medical products are available on Amazon Business, from hand sanitizers to biopsy forceps. According to Chris Holt, Amazon’s B2B Health Services program leader, “there is a needed shift from an old, inefficient supply chain model that runs on physical contracts with distributors and manufacturers to Amazon's marketplace model”.

“If you look at the way a hospital system or a medical device company cuts purchase orders, identifies suppliers, shops for products, or negotiates terms and conditions, much of that has been constrained by what their information systems can do. I think that has really boxed in the way that companies’ function. Modern business and the millennials coming into the workplace, can’t operate in the old way,” says Holt.

Millennials are used to going to Amazon and quickly finding anything they need; even the most obscure items. According to Holt, “A real example is somebody who wants to find peanut butter that is gluten-free, non-GMO, organic, crunchy and in a certain size. And they want to find it in three to five clicks. That’s the mentality of millennial buyers at home, and they want to be able to do the same things at work. . . . The shift from offline traditional methods to online purchasing is very significant. It is our belief that the online channel is going to be the primary marketplace for even the most premium of medical devices in the future. That trend is already proven by data. So, we’ve created a dedicated team within Amazon Business to enable medical product suppliers to be visible and participate in that channel.”

MedTechs fight back

According to the two BCG reports, MedTech companies can fight back by using digital technologies to strengthen and improve their go-to-market activities. This, according to BCG, would enhance MedTechs' connectivity with their customers and help them to learn more about their needs. Indeed, employing digitization to improve customer-facing activities could help standardise order, payment and after-sales service behaviour by defining and standardizing terms and conditions. This could provide the basis to help MedTechs increase their access to a range of customers - clinicians, institutions, insurers and patients - and assist them to tailor their engagements to the personal preferences of providers and purchasers. This could provide customers with access to product and service information at anytime, anywhere and could form the basis to implement broader digitalized distribution management improvements, which focus on value-based affordable healthcare in the face of escalating healthcare costs and variable patient outcomes.

Predictive models

Many companies use predictive-modelling tools to forecast demand and geo-analytics to speed delivery and reduce inventories. Online platforms provide customers with an easy way to order products and services, transparently follow their shipping status and return products when necessary. Barcodes and radio-frequency identification (RFID) chips, which use electromagnetic fields to automatically identify and track tags that contain electronically stored information attached to products, help customers track orders, request replenishments and manage consignment stock.

Back-office improvements

Further, the 2017 BCG study suggests that MedTechs only have made limited progress in improving their back-office operations. Many manufacturers have more employees in their back offices than they do in their customer-facing functions and fail to leverage economies of scale. There is a significant opportunity for MedTechs to employ digital strategies to enhance the management of their back-office functions, including centralizing certain activities that are currently conducted in multiple individual countries.

Takeaway

For the past decade MedTech manufactures have been slow to transform their strategies and business models and still have been commercially successful. Some MedTech companies are incorporating digital capabilities into their products by connecting them to the Internet of Things (IoT), which potentially facilitate continuous disease monitoring and management. Notwithstanding, such efforts tend to be isolated endeavours - “one-offs” - and are not fully integrated into companies’ main strategies. This could run the risk of MedTech executives kidding themselves that they are embracing digitization while underinvesting in digital technologies. The two BCG studies represent a significant warning since digitization is positioned to bring a step-change to the MedTech sector, which potentially could wound successful manufacturers if they do not change.

Each year unhealthy diets are linked to 11m deaths worldwide a global study concludes

Red and processed meat not only cause disease and premature death from chronic non-communicable diseases (NCD) but also put the planet at unnecessary risk

Evidence suggests that the health benefits of a Mediterranean diet reduces the risk of NCDs and is better for the Planet

Eat like Greeks, live healthier lives and save our planet

Findings of an international research project about the relationship between diet and chronic diseases are reported in a paper entitled, “Health effects of dietary risks in 195 countries 1990-2017. A systematic analysis for the Global Burden of Disease Study 2017”, which is published in the April 2019 edition of The Lancet. The paper suggests that millions of people throughout the world consume an unhealthy diet comprised of too much processed meat, sodium and sugar and too little plant-based foods, such as fruits and vegetables, whole grains and nuts. This results in a significant increase in the prevalence of chronic non-communicable diseases (NCD) such as coronary heart disease, cancer and diabetes and each year causes some 11m avoidable deaths worldwide - 22% of all adult deaths: 10m from cardiovascular disease, 913,000 from cancer and some 339,000 from type-2 diabetes. According to the paper’s authors, “Asuboptimal diet is responsible for more deaths than any other risks globally, including tobacco smoking, highlighting the urgent need for improving human diet across nations”.

In this Commentary

This Commentary reviews evidence of recent large-scale epidemiology studies, which suggest that “you are what you eat”. Not only do unhealthy diets cause ill health and premature death for millions, they also harm the environment and push the Earth beyond its planetary boundaries. All the studies we describe conclude that we know the answer to this vast and escalating health problem: eat like Greeks or indeed the Japanese. Notwithstanding, changing the way populations collectively eat is a massive challenge facing governments, healthcare systems and individuals.

The Global Burden of Disease project

The Lancet paper’s findings described above are based on the Global Burden of Disease (GBD) enterprise, which is one of the world’s largest scientific collaborative research projects, which was started in the early 1990s by the World Bankto measure the impact of disability and death from hundreds of diseases worldwide. Over the past two decades its work has grown, and the endeavour has become institutionalized at the World Health Organization (WHO). Today, the GBD project is an international consortium of more than 3,600 researchers, its findings are updated annually and they influence health policy throughout the world.

Red meat and bowel cancer

Findings of a more narrowly focussed but nonetheless significant study, published in the April 2019 edition of the International Journal of Epidemiology warn that red-processed meat consumption is linked with bowel cancer. According to Tim Key, the study’s co-author, Professor of Epidemiology and Deputy Director at Oxford University's Cancer Epidemiology Unit, “Results strongly suggest that people who eat red and processed meat four or five times a week have a higher risk of developing bowel cancer than those who eat red and processed meat less than twice a week . . . . There’s substantial evidence that red and processed meat are linked to bowel cancer and the World Health Organization classifies processed meat as ‘carcinogenic’ and red meat as ‘probably carcinogenic’”. Notwithstanding, Key warns that, “Diet studies are problematic because those who take part often either forget what they have eaten or fail to tell the truth”. Key also suggests that, “Most previous research [on diet and cancer] looked at people in the 1990s or earlier and diets have changed significantly since then”.

Chronic non-communicable diseases

Chronic non-communicable diseases (NCD) are largely caused by humans and are therefore preventable. Notwithstanding, they account for more than 70% of all deaths globally and emergent NCDs pose significant systemic challenges for both nation states and individuals. Forty percent of all adults in the world are overweight and 1.4bn suffer from hypertension: both critical risk factors of NCDs. In 2016, 18m people died from cardiovascular disease (CVD), representing 31% of all global deaths. In the US an estimated 92m adults are living with CVD. By 2030, 44% of the US adult population is projected to have some form of CVD. There are around 7m people living with heart and circulatory disease in the UK. Worldwide some 0.5bn people have diabetes and in 2018 there were 17m new cases of cancer worldwide. Although there are some encouraging signs associated with the slowing of the prevalence rates of NCDs globally, prevalence of NCDs is expected to rise because of population growth and aging, misaligned healthcare policies and institutional inertia.

The paradox of food insecurity and obesity

Paradoxically, food scarcity and obesity are both forms of malnutrition and represent a vast and escalating burden on the worlds limited and diminishing resources. This is because food insecurity can contribute to people being overweight and obese. Nutritious fresh foods often tend to be expensive, so when household resources for food become scarce, people choose less expensive foods that are often high in calories and low in nutrients. As a result, adult obesity rates continue to rise each year, from 11.7% in 2012 to 13.2% in 2016. In 2017 the World Health Organization estimated that more than one in eight adults, or more than 672m people in the world, were obese and 2bn were classified as overweight. A report from the Center for Strategic and International Studies, a think-tank based in Washington DC, US, suggests that worldwide each year, "Malnutrition costs US$3.5trn, with overweight- and obesity-related NCDs, such as cardiovascular disease and type 2 diabetes, adding US$2trn”.

The EAT-Lancet Commission on Food, Planet and Health

Not only do unhealthy diets result in NCDs and premature death, but they also harm the environment. The dual aspects of unhealthy diets causing disease and harming the planet are described in research conducted by the EAT-Lancet Commission on Food, Planet and Health, and reported in the January 2019 edition of The Lancet.

EAT is an independent non-profit organisation based in Oslo, Norway, dedicated to food-system reform, which collaborated with TheLancet. The report took 3-years to complete and brought together 37 world-renowned scientists from 16 countries with expertise in health, nutrition, environmental sustainability, food systems, economics and political governance; and tasked them with reaching a consensus that defines a sustainable “healthy planetarydiet”, which the authors suggest approximates a Mediterranean diet, see below.

The EAT-Lancet research, financed by the Wellcome Trust,analysed the diets of people in 195 countries using survey data, as well as sales data and household expenditure data to estimate the impact of unhealthy diets on the risk of death and morbidity from NCDs. The Commission’s authors provide a comprehensive picture of the consumption of 15 dietary factors across nations and quantify the potential impact of suboptimal intake of each dietary component on NCD mortality and morbidity among 195 countries. Also, researchers calculate mortality related to other risk factors,such as smoking and drug use, at the global level.

The EAT-Lancet Commission’s report has its critics. One is the UK’s National Farmers’ Unionwhose Vice President Stuart Roberts said, “Scientific communities agree that red meat plays a vital role in a healthy, balanced diet as a rich source of essential nutrients, minerals, amino acids and protein. It is overly simplistic to target one food group for a significant reduction in consumption, and it ignores its medically accepted role as a key part of a healthy, balanced diet . . . It is clear that climate change is one of the greatest challenges of our time and British farmers are continuing to take action. A combination of policies and practises will be needed to enable farmers to meet their ambitions, but we must not forget the impact of a changing climate on food production”.

Benefits of red meat

Roberts is right to point out that red meat has health benefits. Heme iron, which is found in red meat (also in poultry, seafood and fish) is easily absorbed by your body and is a significant source of your dietary iron. Red meat also supplies you with vitamin B12 and zinc. The former is required for red blood cell formation, neurological function and DNA synthesis, and the latter helps stimulate the activity of at least 100 different enzymes and helps to keep your immune system working effectively. Further, red meat provides protein, which helps to build your bones and muscles. People have been eating meat for millennia and have developed digestive systems well equipped to handle it.

Notwithstanding, the overwhelming majority of red meat consumed in the developed world today is processed: raised in a factory environment, fed grain-based feed and given growth-promoting hormones and antibiotics and some animals, after being slaughtered, are further treated with nitrates, preservatives and various chemicals. The findings of all three studies described above demonstrate the harm of eating too much red and processed meat and stress the health and environmental benefits of a Mediterranean diet.

An urgent challenge

According to the EAT-LancetCommission’s authors, “Providing healthy diets from sustainable food systems is an urgent and pressing challenge”. As the global population continues to grow - projected to reach 10bn by 2050 - and become wealthier, there is expected to be a concomitant increase in unhealthy diets comprised of red meat, processed food and sugar. To address this vast and escalating challenge, populations will need to combine significant dietary changes with enhanced food production and reduced food waste.

The impact of food waste

Before broaching some of the challenges associated with changing the way we eat collectively let us briefly describe the magnitude and effect of food wastage. According to the United Nation’s(UN) 1.3bn tonnes of food are wasted every year, which is about 33% of the total produced. The cost of global food losses and waste amounts to roughly US$990bn and yet some 800m people worldwide do not get enough to eat and 2bn people are overweight.

Further, food wastage is estimated to release the equivalent of 3.3bn tonnes of CO2 into the atmosphere each year. The total volume of water used annually to produce food that is lost or wasted (250km³) is equivalent to three times the volume of Lake Geneva. Similarly, 1.4bn hectares of land - 28% of the world's agricultural area - is used to produce food that is lost or wasted. And agriculture is responsible for a majority of threats to at-risk plant and animal species tracked by the International Union for Conservation of Nature.

Changing what we eat and how we produce food will save lives and the planet

According to Alan Dangour, Professor in Food and Nutrition for Global Health at the London School of Hygiene & Tropical Medicine(LSHTM), “The EAT-Lancet Commission’s analysis demonstrates that shifts in our diets can have enormous beneficial effects on health and also substantially reduce our impacts on the environment. This significant ‘win-win’ for health and the environment is not a new finding, but this analysis, which for the first time defines environmental boundaries for the food system, is the most advanced ever conducted”.

In a similar vein, Tara Garnett, a contributor to the EAT-LancetCommission and a principal investigator of another research project on the future of food, also suggests that there’s nothing new in the Commission’s report but its fundamental message is that, “We’re not going to address our environmental problems unless we address the problems caused by the food system and we’re not going to address the problems caused by the food system unless we shift the way we eat collectively and globally”.

Rebalancing unhealthy diets is a significant challenge

Changing how we eat collectively, which Garnett and others suggest is necessary to reduce NCDs and enhance our environment, is not going to be easy. This is because it would involve cutting by half our consumption of red meat, processed food and sugar, and doubling our consumption of vegetables, fruit, pulses and nuts. For people living in the US and UK it would be even more challenging because the EAT-Lancet Commission ranks the US 43rd and the UK 23rd for their respective unhealthy diets out of the 195 nations in its study. It is suggested that in order to adopt a healthy diet Americans would need to eat 84% less red meat and six times more beans and lentils, and British people would have to eat 77% less red meat and 15 times more nuts and seeds.

Countries with the lowest rates of diet-related deaths are Israel, France, Spain and Japan. The highest rates are reported to be found in Uzbekistan, Afghanistan and the Marshall Islands. According to the Commission’s authors a Mediterranean-type-diet, “is what we should all be eating if we are concerned about our health and that of the planet”: it lowers the incidences of heart disease, diabetes and cancer, enables more environmentally helpful use of land and reduces carbon emissions.

The Mediterranean diet

The Mediterranean diet has been around for millennia and tends to be more of a lifestyle than a diet. It entails significantly lower amounts of beef, dairy products, sugar, soft drinks, pastries and processed foods; higher amounts of fish, fruit, nuts and salads, and no pasta, French fries and pastries. Unlike fashionable commercial diets associated with the weight management market, the Mediterranean diet does not have a set of specific rules that focus on losing weight, but instead emphasises eating fresh food over a lifetime. Also, the Mediterranean diet has been well studied. Research suggests that it is associated with a reduced risk of heart disease and cardiovascular mortality because of its significantly lower amounts of oxidized low-density lipoprotein (LDL) cholesterol, (the "bad" cholesterol) which is more likely to build up deposits in your arteries. Other benefits include reduced incidence of cancer, Parkinson's and Alzheimer's diseases. Further, women who follow a Mediterranean diet have a reduced risk of breast cancer.

The PREDIMED study

Findings of a landmark clinical trial, entitled “Primary Prevention of Cardiovascular Disease with a Mediterranean Diet”, was published in the June 2013 edition of the New England Journal of Medicine (NEJM). Popularly known as the PREDIMED study (Prevencion con Dieta Mediterranea), it tested the impact of two Mediterranean diets on cardiovascular risk. The first included a Mediterranean diet plus 30 grams of mixed nuts per day and the second was a Mediterranean diet plus at least four tablespoons a day of extra-virgin olive oil. The two diets were then compared to a low-fat diet, which is popularly advocated and pursued in the US and UK and among other developed nations and discourages the consumption of any high-fat items such as butter, cheese, oil, meats and pastries.

The low-fat diet

In the 1960s low-fat diets as opposed to high-fat, high-cholesterol diets were considered to promote heart health. By the late 1980s and early 1990s the low-fat diet was advocated by doctors, policy makers, the food industry and the media although there was no hard evidence to demonstrate it prevented heart disease and promoted weight loss. Notwithstanding, the low-fat-diet became an important part of the large and rapidly growing global weight management market, which is valued at some US$169bn and projected to grow at a CAGR of 2.4% and reach a value US$279bn by 2023. Interestingly, in the 80s and 90s, as the low-fat diet became an institution in the US and UK so the prevalence of overweight and obesity increased. Only recently has the low-fat diet been challenged as scientific evidence about fats increased.

A significant study with some methodological challenges

The PREDIMED study involved 7,447 people between 55 and 80 who were free from heart disease, came from 11 study centres across Spain and were randomly assigned to one of the three diets for five years. Findings suggested that the Mediterranean diet significantly reduced the risk of heart attack, stroke and cardio-vascular mortality compared to the low-fat diet. However, researchers discovered flaws with the study’s methodology and withdraw their findings. Most significantly, not all participants were randomly assigned to their diet and this could have influenced their findings.

Revised study of the Mediterranean diet

Researchers adjusted their methodology for its "irregularities in the randomization procedures" and published “new” findings in the June 2018 edition of the New England Journal of Medicine(NEJM), which confirmed the health benefits of a Mediterranean diet for adults at high risk for heart disease and found that the Mediterranean diet, plus olive oil or nuts, reduced risk for heart events by 30% compared to a low-fat diet. Lead author Miguel Ángel Martínez-González suggested that only about 10% of participants were affected in their earlier study reported in 2013, and their 2018 analysis made researchers, "More convinced than ever of the robustness of the protection by the Mediterranean diet against cardiovascular disease”. According to Jeffrey Drazen, editor-in-chief of the NEJM, "Medical professionals and their patients can use the republished information with confidence". While reaction to the study’s initial findings was disappointing, experts are encouraged by the adjusted findings, which confirm the heart-health benefits of a Mediterranean diet, particularly in adults at high risk for heart disease. Notwithstanding, experts emphasise the significance of sustaining a healthy diet over time.

The health benefits of the Japanese diet

The Mediterranean diet is not the only diet, which has proven to have significant health benefits. The Japanese diet, which is low in calories and saturated fat and high in nutrients, especially phytonutrients such as antioxidants and flavonoids, found in different coloured vegetables, also has considerable health benefits. Findings of two studies; one published in the April 2017 edition of PLOS.ONE, and another published in the March 2016 edition of the British Medical Journal demonstrate that, closer adherence to a Japanese diet resulted in a significantly lower risk of death from NCDs and in particular from cardiovascular disease or stroke. Japan has the highest life expectancy of any country: 90 years for women and 84 for men. Okinawa, in southernmost Japan, has the highest number of centenarians in the world as well as the lowest risk of age-related diseases such as cancer and heart disease. There are nearly 800 centenarians in Okinawa, which has a population of 1,368,000. The diet of the Okinawan people has been little influenced by the dietary changes influenced by western culture, which also have been seen in more urban Japan.

Takeaways

All the research findings we describe in this Commentary confirm the adage that, “You are what you eat”. Nutrients from the food you eat provide support for all the cells in your body, which have different “shelf lives”. For example, your skin cells live for about a month and your red blood cells for about four months. So, your body is constantly regenerating new cells to replace those that have “expired”. The health of your new cells is partly determined by how well you have been eating. A diet high on processed red meat and low on nutrients does not help in this regeneration process. But a nutrient rich, whole food diet can help to build your cells so that they work better to help you recover from common illnesses and the wear-and-tear of everyday life and make you less susceptible to disease.

Although our concern about healthy eating has intensified in recent years, the phrase, “you are what you eat” is not new. In 1826 Anthelme Brillat-Savarin wrote in Physiologie du Gout, ou Meditations de Gastronomie Transcendante, "Dis-moi ce que tu manges, je te dirai ce que tu es" [Tell me what you eat, and I will tell you what you are]. However, the phrase did not emerge in English until the 1920s when nutritionist Victor Lindlahr, who believed that food controls health, developed the Catabolic Diet. According to Lindlahr, "Ninety per cent of the diseases known to man are caused by cheap foodstuffs. You are what you eat". And in 1942, he published a book entitled, “You Are What You Eat: how to win and keep health with diet”. Eat like the Greeks, live healthier lives and save our planet.

What is HIV?

HIV (the human immunodeficiency virus) is a serious viral infection that is spread through body fluids, including through sexual intercourse, and this includes vaginal, anal and sometimes oral sex. HIV can also be spread by needle stick contamination, by sharing needles, receiving surgical treatment in foreign countries (where sterilization of equipment may not meet the standards of developed countries) and sometimes it can be passed from the mother to a child during the birth process or through breast feeding.

HIV is found in the bodily fluids of an infected person which includes semen, vaginal and anal fluids, blood and breast milk. HIV cannot be transmitted through sweat or urine. It thrives inside a persons body, however does not survive long outside the body.

What are the symptoms of HIV?

Not everyone that is infected by HIV will show signs or symptoms of the infection. At first individuals may experience flu-like symptoms, these can include:

diarrhoea

headaches

fatigue

sore throat

muscle aches and pains

If these symptoms do occur they can subside for a number of years and the HIV can go undetected in the body, but during this time the virus will multiply and can be passed on to other people.

What's the big deal with HIV?

If left alone and not managed or treated with antiviral tablets, the infection can lead on to a condition called AIDS (acquired immunodeficiency syndrome), where the immune system becomes weakened and this could eventually lead to life threatening infections and even cancers.

AIDS is the last and final stage of the HIV infection; this is when your body can no longer fight the infection.

However, if caught early through testing, with the correct antiviral medication, most people with HIV will not go on to develop AIDS.

Around 20% of people living in the UK with HIV are thought to be undiagnosed and are unaware that they are carrying the infection. This increases the risk to their partners and themselves of developing serious ill-health problems.

If you have have had sex with someone who may be HIV positive you can reduce your chances of infection by starting a PEP (post-exposure prophylaxis) treatment within 72 hours of exposure to the virus. You will need to attend your local A&E department for this treatment.

HIV home testing

A discreet Test kit is provided simply at home & sample then forwarded to the laboratory using our self addressed envelope.

If you think you have been exposed to the risk of HIV then you should get tested immediately.

TESTD™ offers the latest in HIV testing technology. If you are generally concerned for your health and would like total peace of mind we offer a next day 5th Generation HIV Duo test. This is the most advanced method of testing for HIV and can be done from day 28 onwards following a potential exposure.

The 5th generation HIV Duo test looks for both antibodies and the p24 antigen for HIV and is incredibly accurate (over 99.9% sensitivity).

Please note that it is possible to test for HIV from day 10 after a potential exposure by taking an early detection screen, however it should always be followed up with a 28 day HIV Duo test.

The hayfever injection – help for severe sufferers

Severe hayfever symptoms can ruin peoples’ summers and have a detrimental effect on quality of life and ability to work optimally.

Certain parts of the UK are particularly affected by pollens and allergens likely to give severe symptoms, with the most likely culprits being a mixture of flower and tree pollen such as silver birch and rape seed.

If you have severe symptoms that fail to respond to other treatments, such as oral antihistamine medications, topical eye drops and so on, it is possible to request an appointment to discuss the hayfever injection at our clinics in Nottingham, Derby, Leicester, Sheffield, Leeds and Watford.

The hayfever injection is a corticosteroid injection which has anti-inflammatory properties. It suppresses the immune system and stops the natural pollen response from going ‘haywire’. This is the same medication given by doctors regularly for tennis elbow, various ligament and muscular strains, osteoarthritis and other joint conditions.

As with all injected medications, and in line with good medical practice, the doctor will undertake a careful risk assessment to make sure that you are a good candidate for treatment, and will explain the potential side effects and likely benefits in detail.

In our twenty-year experience of administering the hayfever injection, we have seen virtually nothing in the way of even mild ‘side effects’ with two people reporting a dimpling of the skin at the site of the injection (the buttock).

This dimpling is uncommon, however patients are always advised that it may occur and like all administered medications, the risks of any treatment must be balanced against the potential benefit of the treatment given.

On the 26th March 2019 Bloomberg Businessweek published an article entitled, "The World’s Cheapest Hospital has to Get Even Cheaper”, which describes one of India’s largest private hospital chain's - Narayana Health - response to Modicare, a signature initiative by Prime Minister Narendra Modi to provide basic healthcare for 500m of India’s poorest.

Devi Shetty, a world-renowned cardiac surgeon and chairman of Narayana Health, is up for the task. Since Shetty founded Narayana in 2000 it has grown to become a large multi-speciality hospital chain, comprising 31 state-of-the-art tertiary hospitals across 19 cities, employing 16,000 and each year treating over 2.5m patients across more than 30 medical specialities. Shetty’s mission is to provide high quality, affordable healthcare services to the broader population in India and he is convinced that quality and low-cost healthcare are not mutually exclusive. In conjunction with the state of Karnataka, Shetty has created a health insurance plan, which has enrolled some 3m poor people at an annual premium of about US$2.6. More than half of Narayana’s cardiac operations are performed on patients too poor to afford the full cost. In addition to the insurance scheme free or subsidized inpatient care is achieved through philanthropy and a cross-subsidy model, in which higher-income patients pay more for nonclinical amenities, such as private recovery rooms. Since the total charges are still far below the cost of comparable services at other private Indian hospitals, Narayana Health remains an attractive option for such consumers. Narayana Health’s business model is sustainable because of its ability to attract so many patients who can pay full price. The Wall Street Journal has dubbed Shetty, The Henry Ford of Heart Surgery because he applies assembly line concepts to surgery in order to optimize productivity, minimize costs and leverage economies of scale. Because of these innovations the average cost of open-heart surgery, as reported by Narayana Health, is less than US$2,000. The same procedure at a US research hospital typically costs more than US$100,000.

Since 2012 HealthPad has worked closely with Devi Shetty. We published our first Commentary about Narayana Health and Devi Shetty’s model for affordable quality healthcare in 2013 and in subsequent years published two more. Shetty and his fellow senior surgeons have contributed over 700 videos to HealthPad’s content library, which address FAQs across 11 clinical pathways. Further, Narayana’s clinicians havefeatured in HealthPad Commentaries on Chronic obstructive pulmonary disease (COPD),Diabetes and Kidney Disease and Cardiovascular Disease. Because of the large and growing international interest in Shetty’s alternative model for affordable healthcare we re-publish lightly edited versions of HealthPad’s three Commentaries about Narayana Health.

In 2011 Devi Shetty, an Indian doctor, received the coveted business process innovation award in London from The Economist for his contribution to global healthcare. Trained as a cardiac surgeon in the UK, Shetty returned to India and started a hospital in Bengaluru in 2000. Today, Shetty is on the cusp of changing healthcare in the 21st century.

Shetty’s no-frills hospital chain

In 2012 Shetty launched the first in a chain of no-frills hospitals: a 200-bed single-storey clinic in Mysore, India. Built in 10 months for US$7m, it charges only US$800 for open heart surgery. Shetty rejected the multi-storey hospital model, because it requires costly foundations, steel reinforcements, lifts and complex fire and safety equipment. Much of the Mysore building was pre-fabricated. Its five operating theatres and intensive care units are the only air-conditioned places and families are encouraged to provide supplementary care for patients.

Shetty’s no-frills hospital chain owes its existence to his pioneering hospital in Bengaluru.

Shetty’s medical city in Bengaluru

In 2000 Shetty started Narayana Hrudayalaya, a specialist hospital for cardiac surgery, which today performs the highest number of heart surgeries in the world for any one hospital: 7,000 annually and does not compromise on quality. “We are only technicians,” says Shetty. ”We realised that as you do more surgical procedures, your results get better, and your costs go down. In the US the average cardiac surgeon does about 2,000 surgeries in his or her professional lifetime. We have surgeons who have done more than 3,000 surgeries and they’re only in their 30s . . . imagine the expertise that they have, at that young age.”

Medicines and associated hospital costs in India are significantly lower than in the West, but Narayana offers Indian patients value for money. The average price for open heart surgery in Narayana is around US$2,000, compared to US$5,000 in the average private Indian hospital and $20,000 to $100,000 in a US hospital.

Shortly after starting his Bengaluru cardiac centre, Shetty acquired a 35-acre site next door and built a 1,400-bed cancer hospital and a 300-bed eye hospital and created Narayana Hrudayalaya Medical City, which has 3,000 beds in Bengaluru and is run at near to full capacity. In total Narayana has some 7,000 beds in a number of clinics and hospitals throughout India, and plans to expand to 50,000 beds in the next five years.

Tele-medicine

In association with India’s Space Research Organization, Sherry's Bengaluru hospital runs one of the world’s largest tele-cardiology programs, which reaches 100 facilities throughout India, over 50 across Africa and Narayana’s doctors have treated some 70,000 patients remotely. Narayana Health also disperses 5,000 kidney dialysis machines, which makes the company India’s largest kidney-care provider.

Health insurance

With the state of Karnataka, Shetty has created a health insurance plan, which has enrolled some 3m poor people at an annual premium of about US$2.6. Last year, about 60% of Narayana Hrudayalaya cardiac operations were performed on patients too poor to afford the full cost.

Shetty however is not a charity. His hospitals treat a cross section of patients at variable rates but refuse to turn away anyone who cannot pay. “Charity,” he says, “is not scalable. Good healthcare depends on good business.” Shetty’s hospital group earns an after-tax profit of 8%, slightly above the 6.9% average for a US hospital.

Health City Cayman Islands

Shetty has now turned his attention outside of India and is engaged in a joint venture with the government of the Cayman Islands and a group of American institutional investors, to construct and operate a hospital in Grand Cayman to capture share from the North and South American healthcare markets.

The first phase, a 140-bed tertiary care facility for cardiac surgery, cardiology and orthopaedics, was opened in 2014 and benefits from the cost-effective healthcare procedures honed by Shetty over the past decade. By 2020, the Cayman enterprise, which also will have a medical university and an assisted-care living community, is projected to expand into a 2,000-bed Joint Commission International-accredited Health City providing care in all major specialties.

Super-size hospitals

At a time when the global healthcare debate is emphasising community based preventative strategies, Shetty’s vision is, “affordable healthcare for everyone in super-size hospitals. Today healthcare has got phenomenal services to offer,” he says. “Almost every disease can be cured and if you can't cure patients, you can give them meaningful lives.” Shetty is driven by the fact that a century after heart surgery was developed only 10% of the world’s population can afford it. Each year, India alone needs 2.5m heart operations and yet there are only 90,000 performed.

"Current regulatory structures, policies and business strategies [for healthcare] are wrong,” says Shetty, “If they were right, we should have reached 90% of the world's population." Recently, he shocked a UK audience of health providers by suggesting that it would be better if England only had three centres for cardiac surgery rather than 22.

The Henry Ford of heart surgery

Sir Bruce Keogh, the UK’s former National Medical Director of the NHS Commissioning Board, once suggested that healthcare in England should become more like retail. Shetty thinks like a retailer, views patients as “customers” and has employed mass production techniques used in the early 20th century to automate the American car industry. Known as, “the Henry Ford of heart surgery”, Shetty has demonstrated that high volume complex surgeries mean better outcomes and lower costs. Similar to what Henry Ford did for the auto industry, Shetty has disaggregated clinical procedures into a number of discrete, standardized, unambiguous units, which can be learnt, practiced and repeated. His methods have successfully reduced hospital costs, increased efficiency, enhanced the quality of care and eliminated clinical mistakes. According to Shetty, “Healthcare has huge variation in procedures, outcomes and costs . . . It is the lack of standardization that contributes to hospital mistakes, high costs and low quality of care”.

Change is inevitable

Shetty is convinced that the dearth of health workers worldwide will force change and increase the use of emerging healthcare technologies. An advocate for open technological systems, he says, “In five years a computer will make more accurate diagnoses than doctors. In 10-years it will be mandatory for a doctor to get a second opinion from a computer before starting treatment.”

Takeaways

Not only will Shetty’s Health City Cayman Islands be a lower cost alternative for North and South American patients, it will demonstrate how over-priced and inefficient hospitals in the West are. However, it is not altogether clear whether Shetty’s formula for low-cost high-quality surgical procedures will be effective outside of India. This is mainly because high quality ancillary services associated with complex surgeries, which are relatively inexpensive in India, tend to be patchy and significantly more costly outside of India. Notwithstanding, Shetty is determined to provide the world with a model of affordable healthcare.

Diabulimia is when people with type-1 diabetes (T1DM) ration their insulin to lose weight

People with T1DM who reduce their insulin lose weight but increase their likelihood of serious complications and death

Diabulimia is neither an official medical nor psychiatric disease state but its prevalence is relatively high and increasing

Diabulimia is challenging to diagnose partly because it is a portmanteau of 2 separate conditions and people with the condition often keep the bulimic aspect secret

Recently research into the condition and a clinic dedicated to diabetes and eating disorders have been launched in London

These initiatives are expected to increase our understanding of diabulimia, improve screening and treatment options and provide integrated medical and psychiatric support for people with the condition

Diabulimia - the world's most dangerous eating disorder

In January 2019 the UK’s National Institute for Health Research (NIHR) awarded clinician scientist Marietta Stadler, from King's College Hospital, London, £1.2m to fund research into diabulimia, an eating disorder in which people living with T1DM deliberately and regularly restrict their prescribed insulin dosage for the purpose of weight loss.

Diabulimia is a media-coined term and only recently has it been considered as a separate disease state although it is still not formally recognised as such. We start this Commentary by briefly describing some aspects of the history of the condition.

On 27th September 2011 Sian, the 24-year-old daughter of UK parliamentarian George Howarth, died from complications related to T1DM. As a teenager Sian had not kept up with her medication, she had missed appointments with doctors and dieticians, and was suffering from depression as a result of the condition. Sian had also developed neuropathy, which is damage to the nerves caused by T1DM. Since his daughter’s death Howarth has campaigned to raise awareness of diabulimia.

On 13th February 2013 the UK’s South London and Maudsley NHS Trust (SLaM) published an article entitled, The Growing Problem of Diabulimia.According to Janet Treasure, Professor of Psychiatry and Director of Eating Disorder Services at SLaM, “it is estimated that 40% of T1DM females aged between 15-30 regularly omit insulin for weight control”.

In the July 2014 edition of Clinical Nursing Studies, a review paper concluded that diabulimia, “is not often recognized by primary healthcare providers or members of the individual’s family. If diabulimia is detected early, interventions can be implemented to minimize the risk of early morbidity and mortality”.

In January 2017 the UK's first diabetes and eating disorder out-patient service began working with young women living with diabulimia. Until then people in the UK with diabetes and eating disorders have been able to seek help for one or the other of the conditions, but never together. At the time of the clinic’s launch, Jonathan Valabhji, NHS England’s national clinical director for diabetes and obesity, said: “As a diabetes clinician I’ve seen first-hand the devastating impact that this condition can have on people and their families, and so these services are an important step forward in the recognition of diabulimia”.

In early 2017 the UK’s National Institute of Health and Care Excellence (NICE) upgraded its guidelines and quality standards for T1DM to feature psychological support related to the increased prevalence of eating disorders and the potential for insulin omission in people with T1DM.

On 2nd November 2017, the Scottish Parliament debated a motion on raising public awareness of diabulimia.

Diabulimia

Diabulimia merges the words ‘diabetes’ and ‘bulimia’. Diabetes is a disease in which your body’s ability to produce or respond to the hormone insulin is impaired, resulting in abnormal metabolism of carbohydrates and elevated levels of glucose in your blood.Bulimia is an eating disorder where you binge on food and then purge it by vomiting, laxatives, diuretics, exercise or other purging behaviours to prevent weight gain. Diabulimia is a term coined by the media and used by the general public. Although not well-known, diabulimia is a dangerous eating disorder among people with T1DM and describes the deliberate and regular administration of insufficient insulin to maintain glycaemic control for the purpose of causing weight loss by ‘purging’ calories via excess glucose in the urine. While not formally recognised either as a medical term or as a mental health condition in its own right, the Diagnostic Statistical Manual of Mental Disorders, (DSM-5), considers that insulin omission in order to lose weight is a clinical feature of anorexia nervosa and bulimia. Diabulimia has also been recognised in the 2017 UK’s National Institute of Health and Care Excellence (NICE) guidance for eating disorders.

Insulin restriction and T1DM

To understand why insulin reduction causes weight loss, it helps to understand T1DM, which is a heterogeneous chronic lifetime disorder for which there is no known cure. T1DM is characterized by the destruction of pancreatic beta cells, culminating in absolute insulin deficiency and accounts for between five and 10% of the total cases of diabetes worldwide. In 2014 there were an estimated 422m people diagnosed with diabetes worldwide. The global prevalence of diabetes among adults over 18 has risen from 4.7% in 1980 to 8.5% in 2014.

Typically, T1DM has an early onset, but can occur at any age. It requires regular daily attention, which for children or adolescents can be daunting. The nutritional anomalies associated with the condition have important consequences (see below) and can be a physical and emotional struggle. To be diagnosed with T1DM represents a hard experience that requires subsequent psychological adaptation. Unfortunately, this often does not occur and can be followed by frustration and the non-acceptance of the disease.

T1DM occurs when your immune system attacks cells in your pancreas that make insulin and renders the pancreas unable to produce the hormone, which is needed to allow glucose (a sugar that circulates in your blood) to enter your cells to produce energy. When you consume food, your body converts it into glucose, which enters your bloodstream. Insulin helps to turn glucose into energy. Without a properly functioning insulin system, your body cannot break down glucose so it stays in your bloodstream and can be dangerous.

If you are a person living with T1DM you must regularly check your blood glucose levels. Based on these levels and what you plan to eat, you must give yourself insulin. If you either fail to do so, or under-dose, your body cannot absorb glucose and it accumulates in your blood, a condition known as ‘hyperglycaemia’, in which case, your body attempts to compensate for the excess glucose, goes into starvation mode and starts to break down muscle and fat, releasing acids called ketones. The ketones build up, leading to diabetic ketoacidosis (DKA), which can be fatal.

Epidemiology

Data from large global epidemiological studies of T1DM reported in a paper published in the February 2014 edition of Diabetes Research and Clinical Practice,suggest that there are 0.5m children aged It is estimated that as many as 11% of adolescent women with T1DM meet the criteria for a full-syndrome eating disorder. This is significant when compared to the incidence of eating disorders among women in general. It is estimated that between 0.5% and 3.7% of women suffer from anorexia nervosa, and an estimated 1.1% to 4.2% of women have bulimia in their lifetime. A paper in the June 2000 edition of the British Medical Journal, suggests that adolescent females with T1DM are 2.4 times more likely to develop eating disorders than peers of the same age without diabetes, and 1.9 times more likely to display symptoms of an eating disorder that does not meet the full diagnostic criteria. Other studies show that about 35% of females with T1DM have diabulimia.

Signs and symptoms

Diabulimia is challenging to diagnose and many primary care doctors and endocrinologists who treat people with T1DM may not recognize diabulimia among their patient population. This is partly because diabulimia is not an officially recognised disease state, partly because eating disorders and diabetes tend to be treated separately by different specialists, and partly because people with diabulimia may be ashamed and reluctant to seek help.

The most obvious sign of diabulimia is weight loss. Another common sign is poor blood-glucose control, as measured by elevated A1c levels, particularly if the person has a prior history of good control. Health professionals may wish to attune themselves to the classic signs of diabetes and the common symptoms of eating disorders. The former includes excessive urination, extreme thirst, constant hunger and fatigue. The latter includes dietary restrictions and heightened concerns about weight and body image.

Manipulating insulin to control weight

At the time of diagnosis with T1DM people have often lost a significant amount of weight. Regular doses of insulin are essential for controlling blood sugar levels and successfully managing the condition. However, a common side effect of such treatment is weight gain, and this can lead to a vicious circle. Insulin therapy can lead to weight gain; increasing weight may require increasing dosages of insulin to control blood glucose, which can lead to increased hunger and dietary intake, which can increase weight and enhanced concerns about body image.

Deliberately not taking or misusing insulin to cause weight loss is a purging behaviour that is uniquely available to individuals with T1DM. Weight loss can be achieved by decreasing the prescribed dose of insulin, omitting insulin entirely, delaying the appropriate dose, or manipulating the insulin itself to render it inactive. But when you have T1DM, you need insulin to live. Without it, you may lose weight, but more significantly you can lose your sight, harm your kidneys, damage the nerves in your feet and threaten your life.

Diets, social media and the thin ideal

The management of T1DM is further complicated because it also entails the careful selection of food, eating precise portions and the constant monitoring of carbohydrates. Because of the early onset of T1DM and the ubiquitous use of social media among children and adolescents, which often propagate the “thin ideal”; it seems reasonable to suggest that children and adolescents with T1DM are inherently more prone to issues revolving around food. Thus, in addition to manipulating insulin many people with T1DM commonly restrict their food intake, engage in bingeing and purging, misuse laxatives and adhere to overly strict exercise regimens to overcome body dissatisfaction.

In the US the cost of insulin results in rationing dosages

It seems worth mentioning that a significant proportion of people with T1DM in the US appear to be forced into a similar state of diabulimia because of the high cost of insulin, lack of medical insurance cover (about 10% of the US population [33m] do not have healthcare insurance), and relatively high levels of co-payments for medical insurance. These aspects of the American healthcare ecosystem tend to drive a percentage of people with T1DM to reduce or ration their prescribed dosage of insulin, and their disease state then assumes similar manifestations to diabulimia.

According to research findings published in the June 2018 edition of Diabetes Care, about 27% of the 1.25m people in the US with T1DM say that affording insulin has impacted their daily life. For people with T1DM, “access to insulin is literally a matter of life and death. The average list price of insulin has skyrocketed in recent years, nearly tripling between 2002 and 2013 . . . . [and] . . . individuals with diabetes are often forced to choose between purchasing their medications or paying for other necessities, exposing them to serious short- and long-term health consequences,” say the authors.

According to T1International, a charity which advocates affordable and accessible diabetes care, "People (in the US) spend most of their life in fear of losing their insurance, of running out of insulin and the cost going up, or of having to stay in terrible jobs or relationships to ensure they keep their health insurance coverage. . . . In the worst case, folks are rationing insulin which has led to many reported deaths and excruciating complications."

Research aimed at improve treatment

Given the extent of diabulimia and the significant medical risks associated with the condition, more clinical and technological research aimed to improve its treatment is critical to the future health of this at-risk population. Stadler’s research referred in the opening paragraph of this Commentary is significant. Interestingly, the National Institute for Health Research only supports projects which potentially have a, "clear benefit to patients and the public". Stadler’s research is expected to take five years, aims to provide a better understanding of diabulimia and devise a 12-module treatment plan for people with the condition.

Clinic for people with diabulimia

People with diabulimia could only seek professional help for their eating disorder and T1DM separately, but never together: that was until January 2017 when an out-patients’ clinic opened in London specifically for people with T1DM and eating disorders. The clinic is led by Khalida Ismail, Professor of Psychiatry and Medicine at King's College, London and the lead psychiatrist for diabetes at King's Health Partners, London, which is comprised of King's College London, Guy's and St Thomas' NHS Foundation Trust, King's College Hospital NHS Foundation Trust and South London and Maudsley NHS Foundation Trust. Ismail wants to unite psychiatrists and diabetes experts. "They never meet patients together and it's an inefficient use of current resources . . . . we'd actually be saving money by joining up services," she says.

Takeaways

Diabulimia represents one of the most complex patient problems to be treated both medically and psychologically. Standard treatments for eating disorders are not usually appropriate for cases of diabulimia. Treatment for eating disorders tend to involve removing the focus on food, which is contrary to best practice for the management of T1DM. It is important for clinicians and researchers to better understand risk factors, screening tools and treatment options for diabulimia. Also, there needs to be better access to diabetes specialist psychological services that can provide the integrated support that people with diabulimia need. The London clinic for diabetes and eating disorders and Stadler’s research are a good start.
